Western leaders seek a peaceful conclusion to the rebellion while supporters of the ousted president take to the streets of Tegucigalpa. President Manuel Zelaya says: 'I want to return to my country.'

TEGUCIGALPA, HONDURAS, AND MEXICO CITY — Honduran security forces Monday fired tear gas at angry protesters demanding the return of deposed President Manuel Zelaya, as leaders of the Western Hemisphere pressed for an end to Central America's first military coup in 16 years.

Troops in battle dress chased rock-throwing demonstrators through the downtown streets of Tegucigalpa, the capital, as a military helicopter whirred overhead. At least 30 people were injured, a Red Cross official said. One man reportedly died after being hit by a truck in an earlier incident.

Honduras found itself increasingly isolated a day after the army arrested Zelaya and deported him to Costa Rica. President Obama said allowing the coup to stand would set a "terrible precedent" that evokes "a dark past," and several Latin countries with leftist governments recalled their ambassadors from Tegucigalpa.

Honduras' de facto rulers also imposed a media blackout, preventing international newspapers from circulating and blocking access to Internet news sites and international cable television news networks.

Zelaya, a leftist whose efforts to change the constitution fueled opposition to his rule, appeared at a summit of regional heads of state in Managua, Nicaragua, and was invited to speak at the United Nations General Assembly today.

Zelaya said he would accept an offer by Organization of American States Secretary-General Jose Miguel Insulza to return to Honduras and would like to make the trip Thursday.

Despite nearly unanimous international condemnation of the coup, the man whom the Honduran Congress named to replace Zelaya remained defiant.

Roberto Micheletti said the Honduran Supreme Court backed the removal of Zelaya, whom it accused of violating the constitution. Micheletti said Zelaya had used his close ties to Venezuela's President Hugo Chavez to drag Honduras to the radical left.

"Eighty to 90% of the Honduran population is happy with what happened," Micheletti told Honduran radio.

Honduras is, in fact, divided. Zelaya has a strong following among the Honduran poor, but he alienated Congress, the Supreme Court and much of institutional Honduras.

In the streets of Tegucigalpa, protests were growing. Several thousand Hondurans, including youths, teachers and workers, converged near the presidential palace early Monday, vowing to occupy the zone until Zelaya returned.

Chanting support for the president known by his nickname, Mel, protesters burned tires and set up makeshift barricades using bricks, stones and metal signs. Some were armed with sticks and clubs and taunted the soldiers. Smoke billowed and traffic snarled badly on blocked streets.

"This is only the beginning," said demonstrator Felix Murillo Lopez, 37, a high school teacher. "For sure, it's going to get bloody."

By afternoon, troops began cracking down. They fired M-16 rifles into the air and tear gas at groups of demonstrators, some of whom hurled stones and broke windows. Most of the violence took place in an area a couple of blocks from the presidential palace, full of small restaurants like McDonald's and Burger King.

"The soldiers beat us like dogs," declared Yamie Viera, 30.

Anata Margarita Medina, a teacher, wept as she recalled how soldiers beat her with a rifle butt.

"Then they dragged me and threw me down some stairs and insulted me and accused me of throwing rocks," she said. "I told them I hadn't, but they kept beating me on the back with their rifles."

The injured included people overcome by tear gas and some with bloodied heads, said Luis Reyes of the International Committee of the Red Cross as he bandaged one bleeding young man. He said 30 people were treated at his station alone.

Bertha Oliva, a human rights activist in Honduras, said her group had reports of 60 people treated at a hospital.

"These people causing this violence are digging their own tomb," Oliva said.

At one point, soldiers rushed into the lobby of the Marriott Hotel, about 100 yards from the presidential palace, to yank away a group of demonstrators who'd sought refuge inside.

Earlier, workers at the telephone company were protesting the installation's takeover by about 50 troops. One man was badly injured after being hit by a truck driven by soldiers and later died, his colleagues said. The incident could not be independently verified. The workers said they wanted to prevent soldiers from making off with the telecommunications equipment.

Before the violence around the presidential palace, demonstrators said they might not have agreed with all of Zelaya's policies, but that using the army to remove him was incorrect.
